Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure cantilever beam assembly. Background Technology

[0002] Steel cantilever beams, as an important structural form, are widely used in building engineering, transportation facilities, and industrial equipment. For example, they are used to support billboards, canopies, monitoring equipment, or as cantilever structures of buildings. In these applications, one end of the cantilever beam is fixed to the main structure, such as a column or wall. This fixed connection point is the hub for the transmission of forces throughout the cantilever beam structure, and the reliability of its connection directly affects the safety of the entire structure.

[0003] In existing technologies, cantilever beams are typically connected to columns using end plates connected with high-strength bolts or by direct welding. While this conventional connection method achieves basic fixation, it has inherent mechanical flaws. All the loads borne by the cantilever beam, including bending moments and shear forces, are concentrated in this relatively small connection area, making it highly susceptible to severe stress concentration.

[0004] Under prolonged static loads or dynamic loads such as wind loads, highly concentrated stress can accelerate the fatigue of materials in the connection area, potentially leading to loosening of connecting bolts, weld cracking, or deformation of the connecting plates. Furthermore, for many outdoor steel cantilever beam structures, their connection nodes are inevitably exposed to natural environments such as rain and humid air.

[0005] Exposed bolts, welds, and gaps between components become channels for rainwater accumulation and seepage, eventually leading to severe corrosion of the connectors and surrounding base material. Corrosion not only weakens the effective cross-sectional area of ​​components and reduces their load-bearing capacity, but also further exacerbates problems such as bolt loosening, significantly compromising the safety and durability of the structure and posing a serious safety hazard.

[0006] Therefore, this utility model proposes a steel structure cantilever beam assembly to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the steel structure cantilever beam assembly, such as insufficient structural strength of the connection nodes, easy stress concentration leading to unstable connection, and easy corrosion of the connection nodes when exposed to the outdoors by rainwater, this utility model aims to provide a steel structure cantilever beam assembly with improved structure that can effectively solve the above problems.

[0008] This utility model provides a steel structure cantilever beam assembly, including: a column, a connecting end plate, fixing bolts, a cantilever beam body, a mounting plate; as well as a reinforcing component and a waterproof component.

[0009] The reinforcing component includes a fixing block, a fixing plate, and a reinforcing plate. The fixing block is fixedly disposed between the web of the cantilever beam body and the connecting end plate. The fixing plate is attached to the flange of the cantilever beam body and the connecting end plate. The reinforcing plate is fixedly connected to the fixing plate. The fixing plate is fastened to the flange of the cantilever beam body by a first fastening bolt and a first nut.

[0010] Furthermore, the waterproof component includes a waterproof cover, which is installed at the connection between the cantilever beam body and the connecting end plate, and the waterproof cover is fixedly connected to the mounting plate through ear plates disposed thereon.

[0011] Preferably, the waterproof component further includes a sealing strip, which is disposed on the edge of the waterproof cover and closely fits the surface of the cantilever beam body and the connecting end plate to form a reliable waterproof sealing structure.

[0012] Preferably, the waterproof cover has an adapter groove, the cross-sectional profile of which matches the cross-section of the cantilever beam body, ensuring a high degree of fit between the waterproof cover and the cantilever beam body, thus creating a good foundation for sealing.

[0013] Preferably, both the ear plate and the mounting plate are provided with mounting holes, and the waterproof cover is fixed to the mounting plate by means of a second fastening bolt and a second nut passing through the mounting holes. This connection method ensures the stability and detachability of the waterproof component installation.

[0014] Furthermore, as a specific sealing implementation method, the waterproof cover has an adapter groove, and the sealing strip is specifically set on the edge of the adapter groove to directly seal the key mating gap.

[0015] Preferably, the reinforcing plate is fixed to the fixing plate by welding. This integrated connection method can provide the most effective structural reinforcement for the fixing plate.

[0016] Preferably, the waterproof cover consists of two interlocking half-covers, which facilitates installation and removal from both sides of the cantilever beam body.

[0017] Preferably, the cantilever beam body is made of H-beams to obtain excellent bending load-bearing performance.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up a reinforcing component, uses a fixing block to form a rigid support between the web of the cantilever beam body and the connecting end plate, and works with the fixing plate and reinforcing plate to strengthen and lock the flange of the cantilever beam body. This solves the problem in the prior art that the cantilever beam connection node structure is weak and prone to stress concentration, leading to loosening or failure of the connection. It achieves the technical effect of significantly improving the strength, rigidity and stability of the connection structure and ensuring the load-bearing reliability of the cantilever beam.

[0020] 2. This utility model solves the problem in the prior art where steel structure connection nodes are exposed to the outdoors and are susceptible to rust due to rainwater erosion, thereby reducing the structural life and safety. It achieves the technical effect of effectively protecting internal connecting parts, preventing corrosion, and extending the service life of the entire cantilever beam assembly outdoors.

[0021] 3. This utility model, through the coordinated design of enhanced components and waterproof components, makes the entire cantilever beam component structure more complete and reliable, easy to install, and has the advantages of high strength and high durability. It can better adapt to harsh outdoor engineering environments and has high practical value. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a steel structure cantilever beam assembly, which aims to solve the problems of insufficient strength of steel structure cantilever beam connection nodes and susceptibility to environmental erosion in the prior art.

[0031] like Figure 1 and Figure 2 As shown, the steel structure cantilever beam assembly includes a column 1, a connecting end plate 4 fixedly connected to the column 1 by fixing bolts 5, a cantilever beam body 2 fixedly connected to the connecting end plate 4, and a mounting plate 7 fixedly connected to the connecting end plate 4. The assembly also includes a reinforcing component 3 fixedly connected to the cantilever beam body 2 and the connecting end plate 4, and a waterproof component 6 protecting the connection. The reinforcing component 3, through the synergistic action of the fixing plate 301, the reinforcing plate 302, the first fastening bolt 303, the first nut 304, and the fixing block 305, improves the structural strength and stability of the connection between the cantilever beam body 2 and the connecting end plate 4. Figure 3 As shown, the fixing block 305 is fixed between the web of the cantilever beam body 2 and the connecting end plate 4, forming a rigid support between the web of the cantilever beam body 2 and the connecting end plate 4, thereby increasing the contact area between the two and dispersing stress concentration. The fixing plate 301 fits against the flange of the cantilever beam body 2 and the connecting end plate 4. The reinforcing plate 302 plays a structural reinforcing role for the fixing plate 301. The reinforcing plate 302 is welded and fixedly connected to the fixing plate 301. The first fastening bolt 303 passes through the fixing plate 301 and the flange of the cantilever beam body 2 and fixes the fixing plate 301 and the cantilever beam body 2 through the first nut 304.

[0032] To address the aforementioned technical issues, the steel structure cantilever beam assembly also includes a waterproof component 6. Furthermore, the waterproof component 6 forms a specific structural fit and connection with the aforementioned mounting plate 7 and the cantilever beam body 2. Please refer to [the relevant documentation / reference]. Figure 2 and Figure 4 The following is a detailed description of the waterproof component 6:

[0033] The waterproof component 6 includes a waterproof cover 601 and a sealing strip 602. The waterproof cover 601 is installed at the connection between the cantilever beam body 2 and the connecting end plate 4 to provide waterproof protection for the connection of the cantilever beam body 2. The waterproof cover 601 has an adapter groove 603, the cross-sectional profile of which is adapted to the cross-section of the cantilever beam body 2. The cantilever beam body 2 is an H-beam. The waterproof cover 601 is composed of two interlocking half-covers. The waterproof cover 601 is also provided with an ear plate 604. Both the ear plate 604 and the mounting plate 7 have mounting holes 10. The waterproof component 6 is fixed to the mounting plate 7 by the cooperation of the second fastening bolt 8, the second nut 9 and the mounting holes 10. The sealing strip 602 is set at the edge of the waterproof cover 601, especially the edge of the adapter groove 603. In the assembled state, the sealing strip 602 fits tightly against the cantilever beam body 2 and the connecting end plate 4, which can effectively prevent rainwater and other external media from corroding the connection of the cantilever beam body 2.

[0034] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0035] As a preferred embodiment, in order to further improve the stability of the connection, the reinforcing plate 302 of the reinforcing component 3 is welded and fixedly connected to the outer surface of the fixing plate 301 to strengthen the structure of the fixing plate 301 and effectively resist the bending deformation that may occur when the fixing plate 301 is subjected to force.

[0036] In another preferred embodiment, in order to ensure the reliability of the waterproof component 6, the ear plate 604 on the waterproof cover 601 and the mounting plate 7 are both provided with mounting holes 10 that are aligned with each other. The waterproof cover 601 is fixed to the mounting plate 7 by the second fastening bolt 8 and the second nut 9 passing through the mounting holes 10.

[0037] As another preferred embodiment, in order to adapt to cantilever beam bodies 2 of different specifications, the cantilever beam body 2 adopts an H-shaped steel structure, which has good bending resistance. At the same time, the cross-sectional profile of the adapter groove 603 on the waterproof cover 601 is also designed to match the cross-section of the H-shaped steel.

[0038] As a specific implementation of the sealing structure, the sealing strip 602 of the waterproof component 6 is not only set at the edge of the waterproof cover 601 and the connecting end plate 4, but also specially set around the edge of the adapter groove 603 to ensure that there are no gaps when it is in contact with the surface of the cantilever beam body 2.

[0039] The working principle of this utility model steel structure cantilever beam assembly is as follows:

[0040] During installation, the connecting end plate 4 is first fixed to the column 1 by fixing bolts 5. Then, the mounting plate 7 is fixedly connected to the connecting end plate 4, and the cantilever beam body 2 is fixed to the connecting end plate 4. At this time, the fixing block 305 of the reinforcing component 3 is placed between the web of the cantilever beam body 2 and the connecting end plate 4 to form a rigid support. Then, the fixing plate 301 with the reinforcing plate 302 is attached to the flange of the cantilever beam body 2 and the connecting end plate 4. The fixing plate 301 and the flange of the cantilever beam body 2 are locked by the first fastening bolt 303 and the first nut 304. Through the synergistic effect of the fixing block 305, the fixing plate 301 and the reinforcing plate 302, the overall connection strength and stability between the cantilever beam body 2 and the connecting end plate 4 are significantly enhanced.

[0041] After structural reinforcement is completed, the two waterproof covers 601 of the waterproof component 6 are aligned and fastened to the connection of the cantilever beam body 2. The adapter groove 603 on the waterproof cover 601 is tightly fitted to the H-shaped section of the cantilever beam body 2. At the same time, the sealing strip 602 on the edge of the waterproof cover 601 is tightly fitted to the surface of the cantilever beam body 2 and the connecting end plate 4. Finally, the ear plate 604 on the waterproof cover 601 is fixed to the mounting plate 7 by the second fastening bolt 8 and the second nut 9, thus forming a fully enclosed sealed structure, which effectively prevents rainwater and other external media from corroding the connection of the cantilever beam body 2, avoids problems such as loose connection due to rust and water immersion, and extends the service life of the cantilever beam component.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
